CVE-2017-12617

What is affected

Vendor	Apache

Weakness	CWE-434

The vulnerability

When running Apache Tomcat, it is possible to upload a JSP file to the server via a specially crafted request. This JSP could then be requested and any code it contained would be executed by the server.

Required action

Apply updates per vendor instructions.

US federal civilian agencies were required to act by 15 April 2022 under BOD 22-01. The deadline is a compliance date, not a measure of severity — it says nothing about how dangerous the flaw is to anyone else.
